Circumstances:
Few minutes after takeoff from San Juan, while cruising along the coast, the pilot informed ATC about the failure of the left engine and was vectored to the nearest airport. The pilot reduced his altitude but as he realized he could not make it, he decided to ditch the aircraft about 400 meters offshore. The airplane quickly sank and was not recovered. A passenger drowned while 11 other occupants were injured, four of then seriously. Few debris were later found.
Probable cause:
Powerplant failure in cruising flight for undetermined reasons. The following factors were reported:
- The aircraft came to rest in water and sank,
- Inadequate preflight preparation on part of the pilot,
- Partial loss of power one engine,
- Left engine failed then the right engine lost power,
- Ditched in heavy sea 900 feet from shore,
- No pre-takeoff emergency briefing.

Circumstances:
Prinair flight PQ277 departed Charlotte Amalie Airport (Saint Thomas Island) at 1715LT for an IFR flight to San Juan. At 17:32, the flight contacted San Juan Approach Control and advised that the flight was maintaining 4,000 feet. The trainee approach controller replied: "Prinair two seven seven San Juan Approach Control radar contact three miles east of Isla Verde fly a heading of two five zero for a vector to ILS final maintain four thousand." Actually the flight was 3 miles east of the Fajardo intersection instead of the Isla Verde intersection which is located about 10 miles west of the Fajardo intersection. One minute later the Heron was cleared to descend to 3,000 feet. At 17:38, after being vectored for a runway 07 approach, the airplane contacted trees and crashed, coming to rest near the top of a knoll in the Sierra de Luquillo mountains at an elevation of about 2400 feet (731 m). The wreckage was found about 24 km southeast of San Juan-Isla Verde Airport and all 18 occupants were killed.
Probable cause:
The vectoring of the aircraft into mountainous terrain, under IFR conditions, without adequate obstruction clearance altitude by a controller who, for reasons beyond his control, was performing beyond the safe limits of his performance capability and without adequate supervision.

Circumstances:
After takeoff from Charlotte Amalie-Harry S. Truman Airport, the twin engine airplane encountered difficulties to gain height. After passing over the end of the runway, the airplane struck a house and crashed. The pilot, two passengers as well as four people on the ground were killed. Eight passengers were seriously injured.
Probable cause:
The accident was probably caused by the combination of the following factors:
- The pilot failed to obtain/maintain flying speed,
- Inadequate preflight preparation,
- The aircraft computed to be loaded to aircraft CofG limits,
- No W&B prepared by the pilot,
- Possible misuse of flaps.

SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the three occupants was found. It is believed the airplane may have crashed into the sea.
Probable cause:
Due to lack of evidence, the cause of the accident could not be determined.

Circumstances:
At liftoff at Charlotte Amalie Airport, the airplane encountered difficulties to gain height, stalled and crashed into the sea. The pilot and seven passengers were killed while four passengers were seriously injured. The aircraft was destroyed.
Probable cause:
It was determined that the pilot selected the wrong runway relative to existing wind component and failed to abort the takeoff procedure. Unfavorable wind conditions (gusting to 25 knots) and an improperly loaded aircraft (CofG) were considered as contributing factors.
